The Alvis 4.3-litre and Alvis Speed 25 were British luxury touring cars announced in August 1936 and made until 1940 by Alvis Car and Engineering Company in Coventry. They replaced the Alvis Speed 20 2.8-litre and 3.5-litre.

The Alvis Speed 25 is one of 18 Alvis Car and Engineering Company Ltd models in the MotorJury library, the catalogue that sets out to hold every car ever made — production, prototype and concept alike. The photography on this page is hotlinked from Wikimedia Commons under an open licence, with the photographer credited on every frame.
The record does not fix a firm introduction year for the Alvis Speed 25, which is itself informative: cars without a clean launch date are usually prototypes, coachbuilt specials, or models whose history was written down long after the fact. The catalogue keeps them anyway, because the odd corners of the record are where the interesting machines hide.
On paper, the Alvis Speed 25 reads like this: the record lists its engine as 4387 cc, 92 x 110 mm / Straight-6, Petrol / 137 bhp @3,600 rpm / 31.48 tax horsepower; kerb weight is recorded at 4144 lb; drive goes through single plate clutch, separate 4-speed gearbox all-silent and all-synchromesh, centre change lever, open tubular propeller shaft with metal joints (arranged in a straight line), spi; the layout is front-engine, rear-wheel-drive. Every figure above is a manufacturer specification carried by the Wikipedia infobox or the open Wikidata record for this model — nothing on this page is estimated, and where a source is silent the row simply does not appear.
Within Alvis Car and Engineering Company Ltd's own catalogue the Alvis Speed 25 sits alongside the Alvis 10/30, the Alvis 12/50, the Alvis 12/70, the Alvis 12/75. The record names the successor = as its predecessor and the sp = uk as its successor, fixing its place in the model line's chronology. Design is credited to class = Full-size luxury car (F). Assembly is recorded at designer =.
This library is generated, verified and rebuilt from the open record on every deploy. The catalogue skeleton comes from Wikidata, specifications from Wikipedia's infoboxes under CC BY-SA, photography from Wikimedia Commons under each file's own licence, and the ownership data from United States federal safety records. Nothing is written by hand and nothing is invented: every fact on this page traces to a public source, and every page is rebuilt nightly as those sources improve. Errors in the source record will appear here too — and disappear the night the source is corrected.
Most car databases stop at series production. This one deliberately does not, because concept cars, racing specials and cancelled prototypes are where the industry thinks out loud — the ideas tested in public years before they reach a showroom. Holding them beside the production cars they inspired makes the lineage legible: nearly every landmark road car in this library has a concept ancestor somewhere in the catalogue, and the connections run through the era links on every page.
What this page cannot yet tell you is what the Alvis Speed 25 costs to live with — that is a different dataset. MotorJury's ownership verdicts are computed from federal complaint and recall records plus EPA economy data, published per model year as the nightly ingest reaches each car. If this model was sold in the United States, its years will surface in the ownership database; browse it live or price any car yourself with the true-cost calculator.
Specifications come from the Wikipedia infobox for this model (CC BY-SA) and the open Wikidata record, and are shown only where a source actually carries them — nothing here is estimated. Figures are manufacturer specifications, not measured results.
